Hello,


 I have a couple MLDs that NO MATTER what combination of frequency or pot adjusting I do, they don't get over 2.5 mh.  I'm really frustrated....  What can I do??

The one you think you fried, set the clock to the lowest and see what happens.

i fried the uart chip - wont get recognized anymore Cheesy - my fault! (+5V to data pin)

HI I hope you are well.
I was hoping for some help/ info. I am new at this.
I purchased 2 moonlanders 2 Iand  have managed to get my two Moonlanders going using your instructions (they are running on a Pi 3 externally powered hub) and i can monitor them.
So far I have tried to mine nyancoin from multiple pools and also XVG.
When I first execute the BFGMiner  i get them mining with  thered led flashing, however, within a minute or two the difficulty on the block goes up and my moonlanders seem to stop mining, green led ok, no red led I have tried the lower difficulty ports on the sites and I have tried changing the difficulty in the start shell script too.

Do you have any ideas?? Are they still mining or have they been frozen out. Is there a work around.

any info would be great

these are cool little machines

thanks

Is there a way to control the fan speed? I bought a replacement fan with the same specs 5v 0.2a but is rated at a higher speed so therefore much louder than the original fan. Can I control the fan speed through the software or do I need to control it through hardware? Thanks.

Im still wondering this myself. Does anybody know?

Stock Fans are dumb and are regulated via voltage. @ 5v they reach about 10k RPM. If your replacement fan has a third yellow wire, you can control it via PWM signal, but that would require and external PWM fan controller.

Sounds like your hub is not providing enough power. Try plugging one at a time and run it at stock 600mhz or below. If it works fine then its a power issue.

No red LED flashing usually means they have stopped mining, but you will also get a notification in bfgminer saying they have stopped mining and it should restart them.

The fan should start working the second you plug it into ANY usb port, as the green led comes on. You don't have to run bfgminer. Note that in some circumstances the fan can be really quiet (I think especially if it is facing downwards). Make sure to double check (I sometimes touch the fan on the backside just to feel), Also check and press on the little white connector, just to make sure it is making proper contact (normally that should always be the case). Also, without power, make sure that the fan can spin freely, if necessary loosen the 2 screws that hold the fan onto the heatsink a little (just a little).

I always thought it would be a nice little Arduino project to pwm control the fans and regulate them via a temp sensor glued onto each heatsink.

I've been toying with about 10 moonlander2's for the past few weeks and have noticed a trend.
several have declining hash rates, that is a device will start at say 4.68 Mh/s and with every refresh the hash rate declines a little until the device is hashing a a few hundred Kh/s or in some cases 0.0Mh/s.

im using two systems to test a RasPi3 with a 49 port block eruptor USB hub and a win 10 Pc with A 13 port Anker hub.
I don't think I have a USB power issue.
HW error rate is under 2.5%
Also I never get the ASIC has stopped hashing message, just a slow decline.

Thoughts or ideas?    Undecided

After receiving a better powered hub today i've started tuning the 3 moonlanders which i currently have.

They are all running stable at 832 clock speed. I've copied the setting for core voltage and memory so all 3 are set in the same way.

HW error rates are at 0.38, 0.06 and 0.94% so thats nice and they are hashing along at ~4.70mh/s each. Quite happy with that figure.

One 'issue' though, 2 of the MLD's reach a temperature of about 51-54 degrees celsius. The third goes up to 72-75 degrees celsius. I've already ordered some external fans so that should bring it down a couple of degrees but other than that, any suggestion as to why 1 of them is running so hot?

Thanks for any ideas Smiley

Check the back heatsink, it could have not been applied correctly. Just put some pressure on it and make sure its stuck on there well.

Not really, just whatever system limit for USB devices is, which is probably around 255. Im sure the pi would start choking way before then.

I found that if the MIners are pointing at vardiff ports and they start to change th difficulty often the ML2s will slowly decrease hashrate to 0 and not auto-restart. So i spend my time trying to find the right dfficulty on the port to match the miner and get enough shares to be meaningful. Try as low as you can go on XVG and look for a fixed diff that works on Nyancoin and see if that helps stability.

I guess that is my question, at what point would the pi start to choke? 10, 20, 50?

Will check that! Also will try a micro adjustment of the core voltage to see if it'll stay running stable and a bit cooler. Am going to get 5 more of the moonlanders, quite pleased with their performance overall Smiley

UPDATE:
Well, tried to turn back voltage a bit, that was a no go Tongue The MLD didn't function anymore at all. Have pressed the heatsink a bit more but did not make much of a difference. Have placed 2 usb fans at the moment so that will help i guess.

Besides that, they are currently drawing 1.8-1.85 amp. Would it be detrimental to the MLD's to up the voltage a bit more and the clock and have them come up to 2-2.1 amp? (In terms of lifespan)

Hello,


 I have a couple MLDs that NO MATTER what combination of frequency or pot adjusting I do, they don't get over 2.5 mh.  I'm really frustrated....  What can I do??

Sounds like your hub is not providing enough power. Try plugging one at a time and run it at stock 600mhz or below. If it works fine then its a power issue.

I wish that was the problem.  My hub is providing 2.4a per slot.  I tried connecting them both solo.  Same exact results...

Great stability. How high you got in freq and Vcore? And temps?
